MGL Avionics User Forum

Hello
Iefis lt Challenger with V16 comm radio, Razor controller, Sandia transponder ans uAvionix ADS B

Using the instructions on the tech support page for iefis lt to v16 comm connections and Sandia Transponder with uAvionix ADS-B. My system is MGL wiring harness with the extender for AOA

I'm getting the red X for both the radio and transponder.

Serial port routing allocations are set to
The MGL NavCom 1 radio is set to SR232 port (1 internal)
The Sandia is set to RS232 port 2 ( external )
The radio, transponder and extender module are all enabled in the equipment list

What am I doing wrong?

Thanks
DEW

have you wired them correctly TX->RX and RX->TX ?

Beats me Rainier
What a depressing thought.
Thats why I bought the prewired harness from MGL.
But it wont surprise. Guess I know what I'll be doing this weekend.

Just a thought - make sure your EFIS is in fact running a later version of firmware - if your firmware does not know the V16 it will not be able to detect it.
